Summary of an article by Kliment Robev
In brief
Kliment Robev examines artificial intelligence as the engine of Wall Street’s rally and warns of the risk hidden in market concentration and excessive expectations.
Key points
- AI is the leading catalyst behind record index levels, and the battle for market share is open only to companies worth trillions of dollars.
- The combined market value of the “Magnificent Seven” is $15.5 trillion — as much as the economies of Japan, Germany, India, the UK and Switzerland combined. They make up about 30% of the S&P 500 and about 40% of the NASDAQ.
- Nvidia has become a gauge of market sentiment: the other tech giants are its customers, so its results serve as a leading indicator for the whole US market.
- “The trap of high expectations”: years of beating forecasts have distorted investors’ expectations, and no company can grow at such rates for ever. If Nvidia slows, it could drag the whole market down with it.
- “Buy the rumour, sell the news” — expectations about AI are already largely priced in.
